It's a fun, polished rhythm game with a good selection of songs. The groups are pretty diverse, so you'll probably find one or at least a character that appeals to you. The characters themselves are fun and cute, and the writing is charming, with more nuance than I would have initially expected.

It's also pretty heavy with gay subtext (if that's appealing to you), and there's a character that goes by they/them pronouns canonically which is pretty cool to see. I have problems with the translation being a little too liberal at times with some choices, and sometimes characters sound a bit more sassy than they normally would? But overall it reads fine.

It's a love letter to vocaloid and the community that formed around it after all these years, and you can tell that it was made with care.

Anyways. I like it! It's fun! It's cute! It rekindled my love for vocaloid!
